PCIe/XAUI Riser Overview
PCIe/XAUI cards are installed on vertical risers. You must remove the PCI cross
beam and relevant riser to access a PCIe/XAUI card.
Caution – This procedure requires that you handle components that are sensitive to
static discharge. This sensitivity can cause the component to fail.
Caution – Ensure that all power is removed from the server before removing or
installing expansion cards. You must disconnect the power cables before performing
this procedure.
You must remove PCIe riser 2 when servicing the SCC module.
You must remove all three PCIe/XAUI risers when servicing the motherboard.
